A 53-year-old woman with a left unilocular cystic goiter of the size of a small orange was reported. Approximately four-tenths of the innter surface was lined with several layered squamous epithelium with few follicles remaining. A gradual metaplastic transition from the follicular epithelium to the flattened cuboidal and to the squamous epithelium was observed. The ultimobranchial body has been understood to be a possible origin of an entirely squamous cell cyst of the thyroid, three of which have been reported. The difference between the ultimo-branchial and metaplastic origins will be discussed, and a new designation-primary (ultimo-branchial) and secondary (metaplastic) squamous-cell cyst will be proposed.
报告了一名53岁女性，其左侧有一个小橙子大小的单房性囊性甲状腺肿。内表面约十分之四衬有多层鳞状上皮，仅残留少数滤泡。观察到从滤泡上皮逐渐化生转变为扁平立方上皮和鳞状上皮。最后鳃体被认为可能是甲状腺完全鳞状细胞囊肿的起源，此前已报告过3例。将讨论最后鳃体起源和化生起源之间的差异，并提出新的命名——原发性（最后鳃体起源）和继发性（化生起源）鳞状细胞囊肿。
